Clear Action Gate

The Vortex® Clear Action Gate™ is designed for use in gravity flow or pneumatic conveying systems up to 15 psig (1 barg) depending on size. Mounted horizontally, the machined square-edged blade of this gate mechanically clears the material from the sealing surfaces on each closing cycle allowing it to discharge beneath the valve.

• Positive seal of materials/dust-tight seal across the blade and to the atmosphere
• Live-loaded, wear-compensating hard polymer pressure plate seals
• Enhance conveying efficiency by preventing air loss
• Constructed from specialized metals and polymers for application-specific durability
• An optional air purge assembly keeps fine materials in the flow stream to prevent them from accumulating in the gate body
• Stainless steel liners protect the gate’s seals from material flow
• No pinch points or exposed moving parts for safety
• Horizontal or vertical orientation
• Narrow profile for applications with limited space

Gravity flow and dilute-phase pneumatic conveying applications. Can handle differential pressures up to 15 psig | 1 barg | 0.1 MPa, depending on gate size. Can be used in pressure or vacuum systems.

Non-abrasive to moderately abrasive powders, pellets, and granules. Modifications are available for handling corrosive materials and/or for wash-down.

Available in round sizes. Square, round or rectangular mating flanges are available.

Standard stud bolt pattern, ANSI #125/150, DIN PN10, JIS 10, Custom flanges are available

Double-acting air cylinder, handwheel/crank, chain wheel, electric actuator

Magnetic reed switches, proximity switches, or mechanical limit switches, and/or a clear bonnet cover for visual indication

Sealed-Body Air Purge Special Service Inlet

ATEX Zone 20 (internal), ATEX Zone 21 (external), FDA

The gate inlet and outlet have 10 gauge flanges with bolt pattern to match a 125/150# ANSI bolt pattern.

Gate blade is electro-polished. Polyethylene (PET or UHMW) pressure plate seals are used to replace nylon. *Additional modifications available based on application.
